(A)
When Steven was a young boy, he moved quite often with his family and so he never had many friends. He spent a lot of time on his own and liked to play with electronic(电子的)things. Steven had a neighbour, Steve Wozniak. Steve was a little bit younger than Steven but also liked to play with electronic things. Steven made a microphone(麦克风)and Steve asked him many questions about it until he understood how it worked. Steven liked the fact that such a young boy was also interest ed in electronic things and so he taught him everything he knew.
When they were a little older and knew more about electronic things, they made a “blue box”. People could make free phone calls by breaking into the phone company’s system with this box. They sold this to many people even though it was illegal(非怯的), but this is not why they are famous today.
Steven and Steve were the inventors of the first PC—personal computer. They called their first computer the Apple I. They invented it only for fun and to make themselves known among their friends. They did not think it would become so popular. They just liked playing computer games on it. Their computer made it cheaper and easier for people to own and use a computer. Their PCs were so popular that they made a new PC called the Apple II. Soon many schools, families and factories were using their computers.
Without the two clever men, the personal computers might never have appeared.

(B)
A man had two sons. They were twins. They were born at almost the same time and 1ooked exactly alike．But in one important way, they were very different.
One of them was an optimist, while the other one was a pessimist. An optimist is someone who always thinks that good things will happen. A pessimist is someone who always thinks that bad things will happen.
The man was worried about his sons. There are good and bad things in one’s life. He didn’t want his sons to be too pessimistic or too optimistic. He told one of his friends Johnson this problem. Johnson was a man of many ideas. Then he said, “When is their next birthday?” The father replied, “It’s on Wednesday. They will be twelve years old.”“Excellent, ”Johnson said. “Here’s what you should do. Give your pessimistic son a really wonderful present. Give your optimistic son a really poor present.That will work!
The father did as his friend told him. On Wednesday morning, the two boys got their birthday presents. The pessimist looked at his first. It was a beautiful and very expensive gold watch, but he was not pleased with it. He said, “I don’t like this very much. I’m sure it won’t keep good time. It will always be fast or slow, and it will probably break easily. Then I have to spend lots of money getting it repaired.” Then the optimist looked at his present. He was really pleased. “Look! Dad’s given me shoelaces(鞋带),” he said. He held up the shoelaces and said, “I can use it when I have new shoes.”
36．How were the twins different?

(C) Internet jargons
Recently a father asked a question on the Internet. He asked what “PK” meant. “My family was watching the Super Girl singing competition on TV. My little daughter asked me what ‘PK’meant, but I had no idea, ”said the father.
To a lot of Chinese young people who often play computer games, it is not a new word. “PK” is short for “Player Killer”. In the Internet Games, two players fight until one ends the life of the other.
In the Super Girl singing competition, “PK” means that singers compete with each other. Not all
of them can go up the ranking(名次)。
Like this father, many Chinese teachers have found that their students use many Internet jargons(行话)in their articles. They are difficult to understand. A high school teacher asked her students to write articles in simple language, but they still came up with a lot of Internet jargons. This is a passage written by a student. Can you understand it? “My ‘GG (elder brother) ’ came back this summer from his university. He said I had grown up to be a pretty ‘MM (beautiful girl)’. He took me to the ‘PKM’(short for Pizza Hut, KFC and McDonald’s). ”
Some experts think of Internet jargons as a new development in the language. But some think these jargons are destroying our language. What do you think?
41．By writing the artic le, the writer tries to _______.
A．explain some Internet jargons B．show his worry about Internet jargons C．laugh at the Beijing father D．draw our attention to computer jargons 42．“PK” means ______ in the computer games.
A．player killer B．singers compete with each other
C．game over D．failing the game
43．From the examples of the Beijing father and the high school teacher, we can see that Internet jargons ________.
A．are used not only on the Internet B．can be understood easily
C．are liked by all the people D．are popular with teachers
44．What do the experts think of the Internet jargons?
A．They are all for the Internet jargons B．They are all against the Internet jargons C．Some of them are for the Internet jargons D．None of them is for the Internet jargons 45．Which of the following is TRUE?
A．The father explains the meaning of “PK” on the Internet.
B．Many Chinese yo ung people know the meaning of “PK”
C．“PK” is used only in computer games
D．Only students like to use the Internet jargons.
(D)Teahouses in Chengdu
There is a saying, “China has the best teahouses in the world and Chengdu has the best teahouses in China.”Chengdu has not only many teahouses but also the special ways of serving and drinking tea.
As soon as the visitors enter the teahouses, the waiters or waitresses will greet them with teapots and cups in their hands. The cups often have special covers and saucers(茶碟). The covers can keep the water warm.
People who go to the teahouses are not all thirsty. Retired(退休)people pay a little money to the teahouses and then sit there all day long to chat with others. Sometimes, people have parties in the teahouses. They eat fruit and sunflower seeds(瓜子)while they chat and return home when they are tired. Teahouses are also good places for people to talk about businesses. Some of the teahouses even have stages for performances, such as storytelling, cross talk and Sichuan Opera. Sometimes when people have a quarrel, a mediator(调解员)will bring them to the teahouse. After their problem is solved, the person who is wrong will pay for the tea. It is interesting that as soon as the quarrelers enter the teahouse and sit down to drink tea, they have almost calmed down. With the help of the mediator, their problems can be easily solved then. Maybe we can say the teahouses have some special social functions.
46．Chengdu has the best teahouses in China because _____.
A．the serving of the teahouses in Chengdu is very special
B．there are many people in Chengdu teahouses
C．there are many old men in Chengdu teahouses
D．the cups in Chengdu teahouses are old
47．People in Chengdu’s teahouses may _____ while they are drinking according to the passage.
A．enjoy interesting stories B．watch movies
C．listen to Beijing Opera D．quarrel in loud voice
48．Who will pay for the tea after the mediator solve some problems?
A．The mediator himself B．The person who caused the prob lem
C．All the persons in the teahouse D．The owner of the teahouse
49．This passage is taken from some newspaper. Which part do you think it is from?
A．The sports part. B．The news part.
C．The culture part. D．The education part.
50．This passage mainly talks about _______.

五、阅读表达。(共5小题每小题2分，满分10分)
Thumbs Down to Texting(屈指发短信)
Do you have a mobile phone? Do you send text messages to your friends and family?
Text messaging or “texting”is becoming very popular. ②But, scientists have discovered that texting can cause many problems with our hands. Be careful! Too much texting can cause swelling(肿胀)in our thumbs(拇指). Our thumbs were not made for pushing small buttons(按钮), over and over. Scientists call this problem RSI(重复性紧张劳损). We spoke to a doctor called Harriet Wilson, who treats many ①people ①RSI. She says we need to see how much time we are spending in typing test messages. If we are spendin g more than 10—15 minutes once, we could have problems in the future.
③随着手机的发展，手机正变得越来越小. Texting with a smaller phone, is worse than using a
large phone with bigger buttons. Using a computer keyboard and playing video games can cause the same problem. So more and more peo ple could find themselves with RSI. Among them, most are college students and teenagers, as they do not know the risks of spending so much time using computers, video games and mobile phones. If we don’t do anything about this, too many young people could grow up in terrible pain.
Be careful not to send too many text messages, or you’ll get some problems with your hands. 1．在①句的空白处填入适当的词使句意完整、上下文通顺。

If nothing is done about this, a large number of young people will grow up painfully.

5．找出文中最能表达该短文主题的句子：
______________________________________________________________________
六、缺词填空（共10小题每题1分满分10分）
Ask people to name a safe place and most will say “H 1 .”But every year the British Government’s survey shows that home can be a d 2 place. Last year 7 British citizens died while putting up their Christmas decorations(装饰).Over 1,600 needed medical help after f 3 off their chairs. And 70 people had fatal(致命的)accidents while lying in bed. It is safe to say that n 4
activity is without danger.
Some of these accidents are just the risks of modern living. We prefer to risk having a washing machine that might hurt us r 5 than be safe spending hours cleaning our clothes by h 6 . But most fatal accidents are not the r 7 of mechanical failure. The two most common are falling down the stairs and going to s 8 in the bath. This s 9 that we are in a more dangerous situation when we feel s 10 .

Mackinac Island, Michigan The only way to reach this famed car-free island is by boat and ferry, and once visitors arrive, they're attracted by. the history, scenery and fall colors. "It's a throwback to years past, a little town, and there's a big state park as well," Blackwell says.“You're allowed to have boats all around the island." 2. Tellico Lake, Tennessee With nearly 400 miles of shoreline, this waterway flowing out of the Great Smoky Mountains is largely unexploited, well-protected in its natural state. Fall visitors find a range of colors reflecting in the clean water, says Blackwell, who vacationed in the area-with his family as a child.“The thick forest there just allows you to see more greenery and wildlife. 3. Dillon Reservoir, Colorado With an hour from Denver, this lake is home to what claims to be the nation's highest sailing club, at an altitude of more than 9,000 feet. Marinas in the towns of Dillon and Frisco make it easy to get out on the water and to see the bright yellows and golds of fall leaves.“People are surprised that there's boating in Colorado, and you can see the mountains just before the snowfall," Blackwell says. 4. Lake Monroe, Indiana The state's largest lake is surrounded by more than 13,000 acres of protected forest and three recreation areas, making it an ideal place to see fall colors, particularly from oaks and the tulip poplar, the state tree. " I's a gem(宝石)in southern Indiana" says Blackwell, who grew up in the area. "There are lots of different activities: canoeing, kayaking and fishing. 1. What is special about Mackinac island? A.It's like a modern city, B.Visitors can't take boats around it.
